Is Grey in Norwegian not an appropriate name? English speakers use it, but hey, every culture is different.
There aren't any names that I want to use currently, that would sound wrong in English. But there are English names that I happen to like such as Coy, Dash, Cash, Chase and Trace, and they sound strange to some native speakers. However, those names are popular in the US right now. So, some parents like the names enough to use them, and don't find them inappropriate at all.
Ana might sound weird to some Japanese people, because it sounds like the word "hole". But they still use it if they like. That's because they could use whatever kanji they want in order to change the meaning, or they can give it no meaning by spelling it in hiragana or katakana. They have many options, so there are some girls out there named "Hole", except it doesn't mean Hole.
The name Anna is more popular in Japan than Ana, probably for the reason I stated above.
Some people commented that Jude means "Jew" in German and that Tod means "death" in German. I don't know if that's true, but if so, then I think that a Jude has gone to Germany before, and he has been in for a real surprise - but not really a life-altering one. And the Todd spelling is more common than the Tod spelling, so Todds going to Germany might have better luck... I am not sure. And one Danish commenter said that Tessa meant "to pee" and was outlawed in Denmark.
Practically every name sounds stupid in some language. As long as the name doesn't mean death or disease, its probably not a big deal.
And by the way, according to Wikipedia some traditional Hawaiian names have bad meanings. Some superstitious parents do this to protect the children from curses. I think that the disturbing meanings are meant to humble the children, so no evil spirits will deem vain for having pretty names with nice meanings, like Moana, I suppose. If that's true, then I think that that's considerate of the parents. Kids named Kapuka meaning "Ugly" are not teased in Hawaii, only by foreigners who go there, and do not understand the reasoning behind it. Its considered bad in English culture, but not considered as such in Hawaii, which just so happens to be in an English speaking country. The United States doesn't have an official language. There are numerous languages here, so any name is allowed, I guess? Just not EVERY name.
You know which names are right for your children more than others do.
